We saw 3 lights, as bright as stars in the city, move due south. They seemed to be 1000's of feet above us and moving quite fast. The very weird thing was that they oscillated rapidly in a lateral direction while moving.

My girlfriend and I stepped off of our front porch in downtown Madison, circa December 1999. Looking straight up to see the stars, as I am wont to do, I noticed three lights in a triangular formation moving very rapidly to the South. The lights were about as bright as stars and seemed to be very high in the sky. From the time I noticed them until the time they left the horizon it was, at most, 10 seconds. The thing that was very bizarre was that all three of the lights oscillated or "jiggled" very rapidly in a lateral direction as they flew.
